Kobo Arc EReader Gets Android Jelly Bean Ahead of Kindle and Nook

Only about 16 percent of all Android devices "in the wild" are running the latest version of Android, called Jelly Bean, according to Google's statistics. Most of them are the very latest smartphones, and devices like Google's Nexus smartphones and tablets, which are designed to get updates faster than other Android devices -- especially ebook readers like the Amazon Kindle and the Barnes and Noble Nook, which are so heavily customized that they barely resemble Android.

The Kobo Arc is unusual among ebook readers, in that besides using Google Play for its app market -- which means you can read both Kindle and Nook books on it -- it's also largely based on stock Android. So just a few months after Jelly Bean was released, the update is now available for the Kobo Arc, bringing with it new features and options.

In case you haven't heard of Kobo

Since it's a (Japanese-owned) Canadian company, Kobo's ebook readers are more obscure in the States. They were widely featured in Borders book stores, but ever since the chain closed they're now only found in independent and certain Christian booksellers' stores.

The sequel to the Kobo Vox

Kobo released one color Android tablet, the Vox, in 2011, using older Android software and a slower processor. The Kobo Arc is an all-new model which was released around the same time that Jelly Bean was, in November of last year. It's much more powerful than the Vox, and is roughly on par with Google's Nexus 7 tablet, except for being designed for (and marketed to) ebook lovers and not having Bluetooth or a 3G option.

Jelly Bean's highlights

Kobo's press release spells out most of Jelly Bean's added features: A face unlock feature, a pull-down notification area which lets you act on alerts right from it, and Google Now, which is sort of like Siri. If the Kindle or Nook ever get a Jelly Bean update, many of these features may be rendered useless on them, partly because of how differently they work and partly because neither is Google certified (meaning no Google Now). Amazon and Barnes and Noble do write their own updates, however.

How to get the update

Kobo's press release just says "The update is now available to Kobo Arc customers when they next connect to Wi Fi." If it works like Android OS updates on the Nexus 7, you'll be asked to download the update and restart your device, at which point it will show an Android animation as the update's installed. The process will take a little while, and you may want to leave your Kobo plugged in while it's happening if it's low on batteries.

New assault report similar to Steubenville case

Joan Toribio carries the ball during a game last fall (Torrington High School/Facebook)

On paper, it sounds awfully familiar.

Two high school football players are accused of sexual assault. Their fellow students take to social media to defend the pair, taunting and blaming the victims. An athletic director brushes aside the allegations?along with separate hazing, felony robbery and assault charges against the school's athletes?as "not any different than any other community." Administrators are reluctant to immediately address the accusations and make it appear like a cover-up. The online hacktivist group Anonymous pledges to expose the truth and publicly shame those who engage in cyberbullying and victim-blaming.

Except this isn't Steubenville, Ohio?it's Torrington, Conn., where two 18-year-olds, Edgar Gonzalez and Joan Toribio, stand accused of second-degree sexual assault of two 13-year-old girls. The investigation has led to the arrest of a 17-year-old male for an alleged assault on one of the 13-year-old girls last fall, police say, and more arrests could be forthcoming.

Gonzalez and Toribio, who live in the same Torrington apartment complex, were arrested last month on the sexual assault charges stemming from separate incidents that occurred around the same time period in February, a Torrington police official said on Wednesday. Both pleaded not guilty.

The investigation is ongoing, Torrington police say, and more arrests could be forthcoming.

"It's very involved," Torrington Police Lt. Mike Emanuel told reporters on Wednesday. "It's very difficult to follow, even for us."

The victims and their alleged attackers knew one another, Emanuel said. "The reason that this is a sexual assault is that there is more than a three-year age difference. That's what we have to keep in mind."

When asked if the sexual contact was consensual, Emanuel said, "Statutorily it is not consensual."

Joan Toribio and Edgar Gonzalez (Torrington Police)

Gonzalez, who had already been facing felony robbery charges related to a March 2012 incident, is being held at a New Haven correction center. Toribio, who was charged with two counts of second-degree sexual assault, was released on $100,000 bond and is being electronically monitored.

Sealed by a Litchfield court, the case had been kept under wraps by school officials until this week, when the Register Citizen reported that "dozens of athletes and Torrington High School students, male and female," taunted the victims on Twitter:

Students flocked to social media in the days surrounding the arrests of Gonzalez and Toribio, with several students offering support for the two football players and others blaming the victims for causing the incident. References included calling a 13-year-old who hangs around with 18-year-olds a ?whore,? and claiming the victims ?destroyed? the lives of the players.

"Even if it was all his fault," Mary J. Ramirez, whose Twitter handle is @LoryyRamirez, wrote, "what was a 13 year old girl doing hanging around 18 year old guys[?]"

?I wanna know why there?s no punishment for young hoes,? Twitter user @asmedick wrote, according to the paper.

Torrington school officials said on Wednesday that they would investigate the apparent cyberbullying.

"We?re doing everything we can to provide the safety [the alleged victims] need in schools,? Kenneth Traub, Torrington's Board of Education chairman, said on Wednesday.

As was the case in Steubenville, Anonymous has gotten involved, launching "Operation Raider," a reference to the nickname of the Torrington High School football team.

?#OpRaider is the new #OpRollRedRoll," the group tweeted late Wednesday. "Torrington better take note of #Steubenville because they?re about to go on blast. #endrapeculture"

Toribio and Gonzalez on the field last fall (Torrington High School/Facebook)

High school football takes on elevated importance in Torrington, a small town in northwest Connecticut. "Like Steubenville," Doug Barry wrote on Jezebel.com, the case in Connecticut "hinges in large part on the seemingly disproportionate influence a school?s football program has on the surrounding community."

Despite the felony robbery charges, Gonzalez was allowed to play football last fall.

?I reeled the kid in after that, and he walked the line," Dan Dunaj, Torrington's former head football coach, told the Register Citizen. "As a coach I was doing something right.?

Dunaj resigned in December amid an ongoing investigation into a hazing incident involving four football players last fall.

"If you think there's some wild band of athletes that are wandering around, then I think you're mistaken," Torrington High School Athletic Director Mike McKenna told the Register Citizen. "If you look at crime statistics, these things happen everywhere and we're not any different than any other community."

In an editorial published on Thursday, the Register Citizen blasted "the posture of denial and defensiveness" Torrington school officials have taken in response to the case:

The first step in recovering from this is admitting you have a problem. And after reading the social media accounts of average, "good" students at Torrington High School, it's clear that Torrington students need an urgent education about blaming the victim, bullying and harassment, what "consent" means, why statutory rape is rape, period, and where football should stand in relation to their education and the rest of life. Let's hope that starts today.

Fossil bird study on extinction patterns could help today's conservation efforts

Mar. 21, 2013 ? A new University of Florida study of nearly 5,000 Haiti bird fossils shows contrary to a commonly held theory, human arrival 6,000 years ago didn't cause the island's birds to die simultaneously.

Although many birds perished or became displaced during a mass extinction event following the first arrival of humans to the Caribbean islands, fossil evidence shows some species were more resilient than others. The research provides range and dispersal patterns from A.D. 600 to 1600 that may be used to create conservation plans for tropical mountainous regions, some of the most threatened habitats worldwide. Understanding what caused recent extinctions -- whether direct habitat loss or introduction of invasive species -- helps researchers predict future ecological impacts. The study was published online in The Holocene March 12 and is scheduled to appear in the journal's print edition in July.

"People arrive about 6,000 years ago and within a millennium or two, you lose the big, spectacular critters -- the ground sloths, the monkeys, the biggest rodents and some of the big extinct birds, like giant owls and eagles," said lead author David Steadman, ornithology curator at the Florida Museum of Natural History on the UF campus. "We have some bird species from our fossil site that, from a modern standpoint, are just as extinct as the others, but in fact, they almost were able to survive longer. That helps give us a gauge on what the future might bring."

Researchers used comparisons with modern bones to identify 23 species from the 4,857 bird fossils excavated from Trouing Jean Paul, a cave in southeast Haiti at an elevation of about 6,000 feet. The most common bird species include the Zenaida Dove, the Black Swift, the Least Pauraque, the Hispaniolan woodpecker and a new, undescribed extinct woodcock in the genus Scolopax. Researchers believe the woodcock became extinct between A.D. 1350 and 1800, surviving the first arrival of the Amerindians 6,000 years ago, but dying off following the arrival of Europeans and African peoples in 1492, Steadman said.

"When you take a look at what could've caused this, it really does just keep pointing to humans," Steadman said. "I just think it's habitat loss from people and introduction of non-native, invasive plants and animals. It's the same thing we're dealing with in Florida now -- who knows what the pythons are going to wipe out in the Everglades."

Researchers radiocarbon-dated six individual bones from the extinct woodcock to determine the site's age. Because the locality also includes fossils of frogs, lizards, snakes, bats and rodents, in addition to the Common Barn Owl and Ashy-faced Owl, it was likely a roost where owls deposited boney pellets of their prey, scientists said.

Of the present-day species found at the site, as many as one-third are considered threatened today and four of the 23 total species are no longer found in the area. Their predominant habitat was pine forests, which are mostly disturbed today or entirely cut down for agriculture. The Least Pauraque, a type of nightjar, is now an endangered species that lives in an extremely localized area, Steadman said.

"This gives us some evidence of how drastic the range contraction was of this species -- the Least Pauraque not only lived in the mountains, it was common there," Steadman said. "Within 1,000 years, it's lost most of its range and most of its population. From the standpoint of evolution, if we want that species to ever have the opportunity to evolve through time, we need to be concerned with time intervals that are measured in centuries and millennia, not just decades."

Jim Mead, professor and chair of the department of geosciences at East Tennessee State University, said the research is important because the direct radiocarbon dating represents a much later time period than the arrival of the first Amerindians.

"What Steadman is finding, more often than not, is that we as people bring in other things with us and indirectly wipe out other animals," said Mead, who was not involved with the study. "He's providing background data and I think that's critical to Hispaniola because you have two countries on that island and they're quite different culturally and economically, so those countries are going to play different games on the local fauna."

Mead said it is also significant that Trouing Jean Paul occurs at a high elevation, where human or climate pressures could result in animals finding a "refugia" upslope.

"Typically, a lot of sites are found in lower elevation, or we go to the lower elevations to look at localities we work on," Mead said. "But Dave is saying, 'Why don't we look at these other areas that haven't really been examined?' This one cave is a critical one for that. It gives us a 3-D look at environments on an island."

Oona Takano, who helped sort and identify the specimens as a UF undergraduate student, is a study co-author.

For the first time, recommendations offer guidance about incidental genetic findings

For the first time, recommendations offer guidance about incidental genetic findings [ Back to EurekAlert! ] Public release date: 21-Mar-2013

Recommendations are expected to change the practice of genomic medicine

Boston In a highly anticipated report, landmark recommendations on the handling of incidental findings in clinical genome and exome sequencing are being issued from the American College of Medical Genetics and Genomics (ACMG). A report of the recommendations, led by Robert C. Green, MD, MPH, a medical geneticist at Brigham and Women's Hospital (BWH), outlines for the first time a minimum list of genetic conditions, genes and variants that laboratories performing clinical sequencing should seek and report to the physicians that ordered the testing -- regardless of the original reasons for which the test was ordered.

"If, as expected, these recommendations are adopted by laboratories and clinicians, they will have important implications," said Green, who also co-chaired the ACMG Working Group that developed the recommendations. "As clinical sequencing becomes more widespread, laboratories are looking for guidance on how and what should be communicated to clinicians when results are analyzed. These recommendations will allow a small percentage of families to learn unexpected but potentially life-saving information about an illness they may have never suspected they were at risk for."

The recommendations are the result of a year-long process which included review by outside experts and approval by the ACMG Board of Directors. Leslie Biesecker, MD, chief and senior investigator of the Genetic Diseases Research Branch at the National Human Genome Research Institute co-chaired the working group with Dr. Green.

"Incidental findings" are health-related interpretations of a patient's genetic code that are unrelated to the primary reason for ordering the genetic testing. For example, if a clinician orders exome or genome sequencing to analyze genes related to a patient's cardiac condition, the laboratory will already have information about all the other genes in hand and could examine genes for something like cancer predisposition with relative ease. Should a known or suspected mutation be found in a cancer predisposition gene, the laboratory would report this incidental findings back to the ordering clinician, and the clinician and patient could take steps to screen for cancer. However, in the absence of accepted guidelines about which variants to search for and which results to return to the clinician, laboratories have been uncertain whether to search for or report results beyond those that the doctor ordered.

"We are at an early stage in the implementation of genomic medicine, and this is a difficult topic to manage because there is not yet much scientific evidence to support whether returning incidental findings can provide medical benefit," said Dr. Green. "Based upon existing evidence and clinical judgment, our Working Group of medical geneticists, genetic counselors, ethicists and molecular laboratorians reached consensus that a small number of conditions, genes and variants were likely to have a positive impact on the health of patients and their families if incidentally identified and reported."

In assembling this list, the Working Group prioritized the disclosure of disorders where:

  • Preventative measures and treatments exist
  • Patients might not experience symptoms for a long period of time
  • The genetic mutations are well recognized and known to have a strong link of causation

Examples of diseases recommended for disclosure include rare hereditary cancers and rare heart diseases that could result in sudden cardiac death. The full recommendations are available on the ACMG's website.

Because clinical sequencing is an entirely new technology, the recommendations include several provisions that deviate from established practices in medical genetics. For example, the Working Group did not recommend giving patients a choice of whether or not their physician would receive positive results from the list of recommended incidental findings. The Working Group also recommended that adult-onset conditions on the list be reported even when the patient is a minor. Dr. Green acknowledged that these recommendations diverge from current practices in medical genetics, explaining, "Sequencing offers a brand new way of looking at genetic testing. The Working Group believes that when we can detect findings that could provide clues to a dangerous condition for which a medical intervention may be possible, laboratories and clinicians have a responsibility to alert the patient's physician, as is done in the rest of medical practice."

The report makes it clear that the recommendations are a starting point that will and should be updated regularly as scientific evidence accrues about genetic conditions. The ACMG will establish an ongoing process for updating the recommendations.

Judge appointed to oversee Steubenville case

COLUMBUS, Ohio (AP) ? A large following of "nameless bloggers" alleging a cover-up of a rape investigation spurred an eastern Ohio judge to ask that someone from outside the community oversee a grand jury looking into new charges related to the assault.

Jefferson County Judge Joseph Bruzzese Jr. also asked that outside judges be appointed to prosecute any individuals the grand jury might charge.

In response, Chief Justice Maureen O'Connor of the State Supreme Court on Thursday appointed a retired Summit County judge to handle the grand jury, which meets in April.

Bruzzese noted in his March 14 request "a substantial controversy surrounding this case provoked primarily by nameless bloggers making allegations of cover-up."

"These nameless bloggers, while having produced no evidence of a cover-up have managed to assemble quite a following locally, nationally and internationally," the judge said.

As a result, no local officials should have anything to do with the grand jury proposed by Ohio Attorney General Mike DeWine, Bruzzese said.

Two high school football players were convicted Sunday of raping a 16-year-old West Virginia girl in Steubenville last summer after an alcohol-fueled party. One was sentenced to a minimum of one year in juvenile detention, the other to two years.

A special judge, Thomas Lipps of Cincinnati, handled that case, including the five-day trial last week. Immediately afterward, DeWine announced that a grand jury would investigate whether others should faces charges, including anyone who failed to speak up following reports of the rape.

School officials and Steubenville's 27 football coaches could possibly face charges if they knew about the rape but didn't report it because they are among those required by state law to report possible child abuse.

O'Connor appointed retired Judge Patricia Ann Cosgrove to oversee the grand jury.

Cosgrove is no stranger to high-profile cases. In 2011, she handled the trial of Kelley Williams-Bolar, an Akron woman convicted of falsifying documents to enroll her daughters in the Copley-Fairlawn schools from 2006 to 2008. Gov. John Kasich later reduced the felony convictions to misdemeanors.

In 2005, Cosgrove convicted a prominent Akron restaurant owner's wife of aiding in the drive-by shooting death of a former lover by the third member of a love triangle. Cosgrove sentenced Cynthia George to 20 years to life following the nonjury trial.

Two years later, George was released from prison after the 9th Ohio District Court of Appeals in Akron overturned Cosgrove's decision, ruling the judge lacked sufficient evidence to convict George.

Renewed nuke sale fear after recent N. Korea test

SEOUL, South Korea (AP) ? North Korea's nuclear test last month wasn't just a show of defiance and national pride; it also is advertising. The target audience, analysts say, is anyone in the world looking to buy nuclear material.

Though Pyongyang has threatened to launch nuclear strikes on the U.S., the most immediate threat posed by its nuclear technology may be North Korea's willingness to sell it to nations that Washington sees as sponsors of terrorism. The fear of such sales was highlighted this week, when Japan confirmed that cargo seized last year and believed to be from North Korea contained material that could be used to make nuclear centrifuges, which are crucial to enriching uranium into bomb fuel.

The dangerous message North Korea is sending, according to Graham Allison, a nuclear expert at the Harvard Kennedy School: "Nukes are for sale."

North Korea launched a long-range rocket in December, which the U.N. called a cover for a banned test of ballistic missile technology. On Feb. 12, it conducted its third underground nuclear test, which got Pyongyang new U.N. sanctions.

Outside nuclear specialists believe North Korea has enough nuclear material for several crude bombs, but they have yet to see proof that Pyongyang can build a warhead small enough to mount on a missile. The North, however, may be able to help other countries develop nuclear expertise right now, as it is believed to have done in the past.

"There's a growing technical capability and confidence to sell weapons and technology abroad, without fear of reprisal, and that lack of fear comes from (their) growing nuclear capabilities," Joel Wit, a former U.S. State Department official, said at a recent nuclear conference in Seoul.

Pyongyang says it needs nuclear weapons because of what it calls a hostile U.S. policy aimed at invading the North. An unidentified spokesman for North Korea's Foreign Ministry warned Wednesday of military strikes if the United States repeats recent test flights in South Korea of the nuclear-capable B-52 bomber.

The U.S., South Korea and others say North Korean brinksmanship meant to win aid and other concessions is the real motive. Even China, North Korea's most important ally, opposes its neighbor's nuclear ambitions.

North Korean nuclear sales earn the impoverished country money that can be pumped back into weapons development, analyst Shin Beomchul at the South Korean-run Korea Institute for Defense Analyses in Seoul said Tuesday.

Its growing capabilities could make North Korea more attractive to buyers, especially if it is determined that highly enriched uranium was used in last month's test.

North Korean members of the Worker-Peasant Red Guards attend military training in this picture released by the North's official KCNA news agency in Pyongyang March 13, 2013. North Korea said on March 5, 2013 that it will scrap the armistice signed in 1953 that ended a three-year war with South Korea if the South and the United States continue with two-month long annual military drills.

QUALITY FROM SOURCE. NO THIRD PARTY SALES. NOT FOR USE BY REUTERS THIRD PARTY DISTRIBUTORS less? Proliferation worries have ramped up since late 2010, when North Korea unveiled a long-suspected uranium enrichment operation. North Korea's first two nuclear tests, in 2006 and 2009, were suspected to be fueled by its limited plutonium stockpile. A crude uranium bomb is easier to produce than one made with plutonium, and uranium production is easier to conceal.

Little is known about North Korea's uranium program, but Washington and others are keenly interested in whether it is producing highly enriched uranium for bombs and whether uranium was used in the third test ? two things suspected, but not yet confirmed, by outsiders.

A nuclear test using highly enriched uranium "would announce to the world ? including potential buyers ? that North Korea is now operating a new, undiscovered production line for weapons-usable material," Allison, the Harvard nuclear specialist, wrote in a New York Times op-ed after the North's test.

U.S. officials have hinted that retaliation would follow should Washington discover North Korean cooperation behind any atomic attack on an American city or U.S. ally.

Pyongyang's nuclear transfers and any use of weapons of mass destruction "would be considered a grave threat to the United States and our allies, and we will hold North Korea fully accountable for the consequences," President Barack Obama's national security adviser, Tom Donilon, said last week.

U.S. officials have long tracked North Korean dealings in nuclear and weapons technology. Sanctions have cut down on missile sales, but Iran and Syria, two countries seen by Washington as rogue actors, may continue to be customers.

In November, the head of Iran's Atomic Energy Organization proposed observing North Korea's nuclear test, the Japanese news agency Kyodo reported, citing an unidentified Western diplomatic source privy to Pyongyang-Tehran ties.

North Korea is believed to have helped Syria build what senior U.S. intelligence officials called a secret nuclear reactor meant to produce plutonium. In 2007, Israeli jets bombed the structure in a remote Syrian desert.

Japan's government said Monday that it has determined that a shipment believed to have originated in North Korea violated U.N. sanctions because it contained material that could be used to make nuclear centrifuges.

The shipment of an aluminum alloy was seized from a Singaporean-flagged ship transiting Tokyo last August. The ship was reportedly bound for Myanmar from the Chinese port of Dalian, although Japanese government officials didn't confirm Myanmar as the destination.

Japan's chief government spokesman, Yoshihide Suga, said officials searched the ship because they believed it carried North Korean cargo. News reports said the United States tipped off Japan. Suga said officials had determined in subsequent analyses that the rods were made of an alloy that suggests they were intended for use in a nuclear centrifuge.

Suga said the seizure was the first to be conducted under a law Japan passed in 2010 to clamp down on the movement of materials that could be used for nuclear weapons development being brought into, or exported from, North Korea.

The murkiness of the clandestine nuclear trade is a major worry. It's difficult to know how a buyer would use atomic material or know-how, or where material could end up after being sold.

"The terrorist threat of an improvised nuclear device delivered anonymously and unconventionally by a boat or a truck across our long and unprotected borders is one against which we have no certain deterrent or defensive response," Robert Gallucci, a former senior U.S. diplomat who negotiated a U.S.-North Korea nuclear deal used to defuse a nuclear crisis in the 1990s, said late last month in Seoul.

"For Americans, this threat is far greater than the unlikely threat that may someday be posed by North Korean nuclear weapons delivered by a ballistic missile," he said.
